I'm having difficult understanding the output after running the zpool status command:
NAME STATE READ WRITE CKSUM
tank ONLINE 6 0 0
raidz2-0 ONLINE 0 0 0
c3t0d0 ONLINE 0 0 0
c3t1d0 ONLINE 0 0 0
c3t2d0 ONLINE 0 0 0
c3t3d0 ONLINE 0 0 0
I see a 6 next to READ, which I assume are I/O errors trying to read from tank. What I don't understand is which drive is at fault here to replace. Is this something to be alarmed about? I ran a SMART test and none of the drives reported a fault. I'm not exactly sure how to handle this problem.
